<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js'></script>

Script Preparation code:

var MyObject = {};

// Iterate to big object 10 000 times
for (var i = 0; i < 10000; i++) {
  MyObject['prop' + i] = {
    description: 'Creates a deep copy of source, which should be an object or an array.',
    myNumber: 123456789,
    myBoolean: true,
    jayson: {
      stringify: 'JSON.stringify() method converts a JavaScript value to a JSON string....',
      parse: 'JSON.parse() method parses a JSON string...'
    }
  };
}

var myCopy = null;

Tests:

Lodash cloneDeep
myCopy = _.cloneDeep(MyObject);
Json clone
myCopy = JSON.parse(JSON.stringify(MyObject));
